Words seem to carry far more weight than facts among those liberals who argue as if rent control laws actually control rents and gun control laws actually control guns. It does no good to point out to them that the two American cities where rent control laws have existed longest and strongest -- New York and San Francisco -- are also the two cities with the highest average rents.
Nor does it make a dent on them when you point out evidence, from both sides of the Atlantic, that tightening gun control laws does not reduce gun crimes, including murder. It is not uncommon for gun crimes to rise when gun control laws are tightened. Apparently armed criminals prefer unarmed victims.
Minimum wage laws are another issue where the words seem to carry great weight, leading to the fact-free assumption that such laws will cause wages to rise to the legally specified minimum. Various studies going back for decades indicate that minimum wage laws create unemployment, especially among the younger, less experienced and less skilled workers.
